I have this filter:

    $post_arr = apply_filters('insert_product_post_data', $post_arr, $data);
    add_filter('insert_product_post_data', 'my_filter', 10, 2);
    function my_filter($post_arr, &$data)
    {
    //change $data here
    }

I need to change the value of $data is any way to do this ?
